ScarletRose: Agreed. Therefore I think one shouldn't wait for a person to have answered his/her questions before fielding questions for the next. Why not nominate a candidate four or six times a year (so, once every three or two months), collect questions for a month, and then let the candidate answer them; if it takes the candidate half a year to answer, it wouldn't impact another interview. (And, IMO, if a candidate hasn't answered even a single question a month after all the questions have been collected, just remove the entire interview).
